CVE-2023-50380Network attack vector

Root-level file disclosure via permissive XML parsing

Published Feb 27, 2024 · Updated Mar 27, 2025

XML external entity injection in Apache Ambari 2.7.0 through 2.7.7 allows remote authenticated users to read root-level files. Workflow Manager View's Utils.formatXml method parses attacker-controlled XML with a DocumentBuilderFactory that permits DOCTYPE declarations and external entities. Low-privilege Ambari access is required; successful exploitation discloses arbitrary server files, while privilege escalation remains theoretical.
